Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

A small particle with negative charge q = -12 x 10-3 is traveling between two large parallel plates that have charges of equal magnitude and opposite sign. The speed of the particle is 550 m/s. There is a uniform magnetic field in between the plates with magnitude of 5.0 T and its direction is out of the page. What are the magnitude and direction of the uniform electric field between the plates if the particle travels in between the plates without being deflected?
1) A uniform magnetic field B points in the direction. A circular loop of wire has radius a and resistance R. At t = 0, the loop lies in the x-y plane, with the center of the loop at the origin of coordinates. The loop rotates about the y-axis with angular velocity w. Find the current, I(t), flowing through the loop at an arbitrary time t. (Ignore/neglect any "self-induction" effects, i.e., neglect any effects of the magnetic field produced by the current in the loop.)
